PAPER BAG.

SPECIFICATION forming part of- Letters Patent No. 340,078, dated April 20,1886.

Application filed October 19, 1885. Serial No. 180,265.

To all whom, it may concern:

. Be it known that I, DANIEL APPEL, a citizen of the United States, residing at Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Paper Bags, fully described and represented in the following specication and the accompanying drawings, forming a part of the same.

This invention relates, generally, to that class of paper bags which are made from asinA gle piece of paper which is folded transversely upon itself and united at its edges, so as to form a bag having two side seams and a seamless bottom.

The invention relates particularly, however, to a bag of this class which is provided with what is known as a Satchel-bottom.

The bags constructed according to the pres ent invention may be made from a continuous web or from detached sheets or blanks, the same as is the case with most of the ordinary forms of paper bags. In carrying the i`nvention into practical operation it will usually, however, be found most desirable to employ detached blanks previously cut to the proper form. The operation of making a bag from such a blank is therefore illustrated in the present case.

`As the construction of the bag can be best understood from a detailed description of the manner in which the blank is treated in forming it, such description will now be given, rel" ereuce being had to the accompanying drawings, in which- Figure 1 is a View of a portion of a blank of suitable form for making the bag, the dotted lines indicating the lines upon which the blank is folded in the formation of the bag. Figs. 2 to 6, inclusive, illustrate the various steps in the formation of the bag. Figs. 7 and 8 are views of the opposite sides of the completed bag. Fig. 9 is a perspective view of the bottom of the bag when distended, and Fig. 10 is an inside view of the same.

Referring to said figures, it is to be linderstood that the sheet or blank, a part of which is shown in Fig. 1, is of rectangular form and of the proper length and width to make the bag of the desired proportions. This blank (Model.)

may, and preferably will, be first creased on some or all of the dotted lines indicated to aid in making the several folds necessary in the formation of the bag.

The blank, either with or without the creasing, is tirst folded transversely on the line 10 10, so as to bring the portion B, which forms one side of the bag, over onto the portion C, which forms the bottom of the bag, and the portion A, which forms the other side of the 6o bag, as shown in Fig. 2. This being done, the narrow portion d, at one side of the portion B, is folded inward on the line 12 12, thus at the same time forming diagonal folds on the lines 9 12`at that side of the blank, and bringing the 65 triangular portion b at that side of the blank into the position shown in Fig. 2, so that the line 10 12 will coincide with the line 8 12. The portion d is then folded back to its original position, thus foldingI the portion b upon 7o the line 10 12 and bringing it beneath the side portion, B, as shown in Fig. 3. The portions d and b at the other side ot' the blank are then treated in like manner. The portion d is folded inward on the line 12 12. thus making diag- 75 onal folds on the lines 9 12 at the other side ofthe blank, and bringing the portion b at 'that side of the blank to the position shown iu Fig. 3. The portion d is then folded back to its original position, thus folding the portion 8o b on the line 10 12 and bringing it beneath the portion B. It will of course be understood that both of the portions d may be folded inward and then outward simultaneously, or that the second of the portions may be folded inward before the tirst is folded back to its original position. After the portions bat both sides of the blank have been folded inward beneath the portion B, as j ust described, the portion B is turned upward away from the 9o portion A and is folded outward on the line 13 13, and at the same time diagonal folds are made upon the lines 7 13, which cause the narrow marginal portions e at the edges of the portion Bto be folded inward on the lines 13 15, as shown in Fig. 4. After this is done the side portion, B, and the bottom-forming portion O are folded over on the line 11 11, as shown in Fig. 5, thus causing the lines 13 13 and 14 14 to coincide, and at the same time toc folding the triangular portions a at each side of the blank centrally upon the lines 8 1l and bringing the bottom'forming portion C to the top, where it projects for one-half of its widthv over the side portion, B, as shown in Fig. 5. After this is done the triangular portions c at the sides of the bott-om portion, C, are folded inward on -the lines 8 12 and laid down onto the bottom portion, G, thereby unfolding the folds made on the lines 8 11 and 10 12 and forming diagonal folds on the lines 6 8, and causing the triangular portions a to overlie the triangular portions b, and the lines -8 12, 8 11, and 10 12 to coincide at each side of the blank, as shown in Fig. 6. After this has been done the side portions, A B, are folded over together on the coinciding lines 13 13 and 14 14, thereby carry ing the bottom portion, C, over so that it overlaps the side portion, A, as shown in Fig. 8, and at the same time unfolding the folds on the lines 6 14 and forming the diagonal folds on the lines 5 14, and causing the narrow marginal portions j' of the side portion, A, to be folded over on the lines 14 16 ontoA the opposite side portion, B, as shown in Fig. 7, thus completing the formation ofthe bag.

It will be observed that by this manipulation of the blank a bag is formed which has a seamless satchel bottom. The triangular points formed by the triangular portions c and onehalf of each of thetriangnlar portions a and b, which correspond to the points of the diamond in an ordinary satchelbottom bag which is made from a 'tubular blank, may be pasted down tothe bottom portion, C, or they may be turned-outward and secured in that position so as to .be upon the sides of' the bag when the latter is disteuded, as indicated by dotted It is of course to be understood that the portions f, or both the portions fand e and also the outer edges of the triangular portions a,wil1 be provided with suitable lines of paste to properly unite the plies of the paper to form the seams of the bag. f

In conclusion, it is to be remarked that the folding described may be varied considerably without departing from the essential features of the invention, and also that the form of the blank may be varied from that shown. The narrow marginal portions e may, if preferred, be removed from the blank, and this will somewhat simplify the folding.

. What I claim is* y 1. A bag having two side seams and aseamless bottom, and having the triangular points formed at opposite sides of the bottom byv bringing together the triangular portions cand the portions a b, substantially as described.

2. A bag having two side seams and a seamless bottom, and havingthe triangular points formed of the portions a b c, folded -inward and secured to the bottom, substantially as described.

In rtestimony whereof I have hereunto set y my hand in the presence of two subscribing Witnesses.
